The area of a ferris wheel is about 154 square meters. Which of the following is closest to the length of one of the spokes? [As

babunello [35]

Answer:

The length of one of the spoke is 7 m

Option C is correct answer.

Step-by-step explanation:

Area of Ferris Wheel = 154 square meters.

We need to find the length of one of the spokes.

We are given: Assume the spokes go from the centre to the edge of the Ferris wheel.

So, We are given area of circle and we need to find radius of circle.

The formula used is: $Area\:of\:circle=\pi \:r^2$

Putting values and finding radius

$Area\:of\:circle=\pi \:r^2\\154=3.14\:r^2\\r^2=\frac{154}{3.14}\\r^2=49\\Taking\:square\;root\\\sqrt{r^2}=\sqrt{49}\\r=7\:m$

So, Radius of circle = 7 m

The length of one of the spoke is 7 m

Option C is correct answer.

The population of a certain bacteria doubles in size every 3 hours. If a population begins with one bacterium, how many will the

gladu [14]

There would be 256 bacteria after one day.

There are 24 hours in a day, and the amount of bacteria doubles every 3 hours, so it will double:

24 / 3 = 8 times.

To find the current amount we could use an equation such as:

1 * 2^8 = x

Finally, solve for the number of bacteria:

1 * 2^8 = x

1 * (2 * 2 * 2 * 2 * 2 * 2 * 2 * 2) = x

1 * (4 * 4 * 4 * 4) = x

1 * (16 * 16) = x

1 * 256 = x

x = 256
